Title: Extractor hood fan motor control circuit - uses variable resistance to control transistor circuit across diode rectifier bridge in motor supply
Inventor: PLENER HELMUT ING GRAD
IPC: H02P25/04
Filed: 1980-04-18
Abstract: The speed control circuit for a motor (4)operating a ventilator fan inside a steam and vapour extration hood, has a diode bridge circuit (11) forming a rectifier in the supply line (1,2) for the motor. Also connected across the rectifier bridge is an adjustable load circuit (23) with a transistor (16) having a rotary ohmic resistance (21) with its arm (22) connected to the base (17) of the transistor. This forms a voltage divider, and in series with the variable resistance is a fixed resistance (20) which determines the starting speed of the motor. The voltage of these resistances is connected with the rectified voltage (V1) of the rectifier bridge and modifies it. The transistor is encapsulated and is in the ventilator duct. In parallel with the motor is a capacitor (24). For better speed regulation, a Darlington transistor circuit can be included in the load circuit.

Title: Gas mixt. contg. hydrogen and nitrogen for ammonia synthesis - where hydrogen is purified in adsorbers which are desorbed by nitrogen, and some nitrogen is left in adsorbers
Inventor: FUDERER ANDRIJA
IPC: C01B3/56
Filed: 1980-08-30
Abstract: A first gas mixt. contg. hydrogen and adsorbable impurities is fed through at least one adsorption bed to remove the impurities and obtain a gas rich in H2, which is fed through a second bed at a lower pressure. Nitrogen gas is then fed in the reverse direction through the first bed to remove the impurities by desorption. Some N2 is intentionally left in the first bed, and is compressed together with more gas. After further adsorption of the impurities, a prod. gas mixt. of H2 and N2 is obtd. The pref. plant uses a row of adsorber beds and alternating gas pressures; and the N2 required is pref. obtd. by the cryogenic treatment of air. The O2 obtd. from the air is pref. used in mfg. gas. Increased yield of H2, and lower energy consumption is provided.

Title: Device for complete removal of material heap - has bottom discharge sprung scraper to absorb heap material settling
Inventor: HERING KNUT PROF DR ING
IPC: B65G65/06
Filed: 1980-09-01
Abstract: The arrangement is intended for removing bulk material (23) completely from a heaped supply which may be in the form of a circular cone or a longitudinally extending heap. The material is initially moved under gravity via a central outlet and a conveyor belt in an underground tunnel which leaves a remainder. A scraper conveyor assembly or the like is wholly or partly covered by the material and movable on rails over the base of the heap to remove the remainder. To compensate for the pressure which the material exerts on this assembly as it settles, the assembly has a certain spring resilience, provided e.g. by a false roof carried by springs, or spring-supported rails or by spring action of the box section of the scraper conveyor itself.
Patent DE-3034197-A1 (DE)
Title: Air and watertight blasting fuse - with sealing cap crimped over ends
IPC: C06C5/04
Filed: 1980-09-11
Abstract: Blasting fuse in an air- and water-tight enclosure has both ends covered by a crimped thin-walled sealing cap. At the ignition end, the wall is thin enough to be pierced by the ignition flame of the primer. A sealing hose between cap and fuse assists the tightness. The blasting fuse is enclosed at one end by a sealing hose and a crimped sealing cap. A distance ring outside the powder core supports the end with a thin impressed centre. Opt. the distance ring and the thin centre are replaced by a disc of combustible matter (boron-aluminium-potassium nitrate, nitrocellulose or combustible plastic mixts.). This prevents the access of moisture and air from deteriorating the properties of blasting fuse so that it retains its function after long storage.

Title: Load-dependent braking force regulator - has fingers with recesses tapering towards piston axis in faces against membrane
Inventor: GASSMANN HEINER
IPC: B60T8/18
Filed: 1980-12-23
Abstract: The braking force regulator is dependent on the load. It has a membrane with a variable working surface area, and a support for the membrane with radial fingers fitting between each other. These fingers are fixed half to one and half to the other of two regulator members, whose position in relation to each other in the axial direction varies as the regulator operates, so as to vary the degree of support for the membrane. The fingers (4,6) of one or both members e.g. housing (3) or piston (1), have recesses (11) tapering towards the piston axis in their faces (9,10) in contact with the membrane, and which are deeper than corresponding radial bent sections in the membrane.

Title: Writing and/or drawing instrument and use thereof as a learning toy
Inventor: GERTEIS FRANZ ING GRAD
IPC: B43K23/00
Filed: 1981-01-24
Abstract: Writing and/or drawing instrument with fastening means of a drawing carrier to be inscribed. When stencils are used for writing and drawing, there is the problem of ensuring that the symbols to be reproduced come to rest at predeterminable intervals within a line and from one line to the other, or that, where composite pictures are concerned, fixed relationships between individual figures are guaranteed. This fixed relationship is achieved in that the baseplate (1) of the writing and/or drawing instrument has fastening means (2), for example catch noses, for at least one writing and/or drawing stencil (5, 6, 11, 13). The drawing stencil can itself have fastening means for the fastening of drawing elements (17) to the stencil. To guide a drawing pencil (21) in the cutouts and the symbols to be reproduced, a drawing-pencil holder (18) with a sliding cylinder (20) fitting into these cutouts can be used. The instrument is particularly suitable as a learning toy for the pre-school teaching of children and as a learning aid for special schools.

Title: Heater jet pump
Inventor: KROPLA PETRANA DIPL ING
IPC: F24D19/10
Filed: 1981-02-10
Abstract: The invention relates to a valve arrangement for temperature control, having a valve, if appropriate a thermostat valve, fitted over a sleeve directly on a heater, and having a connection for the supply of the feed water and a device for admixing return water. In such a valve arrangement, an improved utilisation of the sensed heat of the feed water is provided in conjunction with a simpler design and easier assembly due to the fact that the connection opens into a nozzle whose exit jet is directed into a mixing chamber of a diffuser of a jet pump, and that the diffuser projects into the heater while keeping free an annular channel which is connected in terms of flow to the interior of the heater, on the one hand, and to the suction zone of the nozzle outlet jet, on the other hand.

Title: Loudspeaker box constructed as a bass reflex enclosure
Inventor: PULS BERNHARD
IPC: H04R1/28
Filed: 1981-04-02
Abstract: To improve the removal of heat from a closed loudspeaker box, it is proposed to distribute the area necessary for the bass reflex opening over two openings and to arrange in each of the openings an air choke in such a manner that a higher resistance is offered to the air flowing into the housing in one opening and to the air flowing out of the housing in the other opening. This produces air circulation between the space in the loudspeaker box and the space outside.
